The Bonne 1 showing is located on the south side of Bonneau Creek, about 43 kilometres east-southeast of Vernon.
The claims were staked in 1982 and work in 1983, 1984 and 1987 identified geochemically anomalous areas and located zones of altered and silicified outcrop. In 1988, a silicified and pyritic outcrop was discovered during geological mapping, prospecting and geophysics.
The area is underlain by sedimentary and volcanic rocks of the Devonian to Triassic Harper Ranch Group. In the area of the showing these comprise primarily schistose rock but include phyllite, amphibolite and limestone. These have been intruded by granitic rocks of the Jurassic Nelson intrusions.
Quartz veins occur in limestone south of Bonneau Creek on the Bonne 1 claim, about 3.3 kilometres southeast of the Echo II showing (082LSE066). A sample assayed 31.6 grams per tonne silver and 0.53 gram per tonne gold (Sample LES-158, Assessment Report 16413); another sample yielded elevated arsenic values ((Sample LES-204, Assessment Report 16413). The veins occur near the contact with intrusive rocks.
